tinctly converges posteriorly; vertex shining with sparse, well-defined 

 punctures ; postocellar line a little more than half as long as ocellocular 

 line; the third antennal joint about one fifth longer than the fourth; meso- 

 scutum subopaque, with a median depression anteriorly towards which the 

 oblique striato-punctation converges ; posterior margin of the scutum 

 shining; scutellum shining, punctured; dorsal aspect of the propodeum 

 rugose anteriorly, rugoso-granular posteriorly, sides reticulate; petiole a 

 trifle shorter than the hind basitarsis. Black, densely clothed with long 

 gray hair ; wings hyaline, distinctly dusky beyond the basal vein ; venation 

 pale brown, costa and stigma dark brown. 



Type Locality. — Hampton, New Hampshire. Described from one male 

 collected June 28, 1905, by S. A. Shaw, for whom the species is named. 



Type— Ca.i. No. 21563, U. S. Nat. Mus. 



Pemphredon foxii new species. — This species has been confused with 

 concolor by Fox, but the characters given in the above table show that it 

 is easily separated from that species by the puncturation of the scutum 

 and the different conformation of the anterior margin of the clypeus. 



Female. — Length 10 mm. Clypeus subconvex, polished, with widely 

 separated distinct punctures, the anterior margin deeply biemarginate or 

 tridentate with subequal teeth; distance between the eyes at the clypeus 

 somewhat greater than the length of the eye; front shining, medianly 

 sparsely punctured, laterally, the punctures become confluent so there is 

 distinct tendency towards striato-punctation; posterior orbits and vertex 

 polished, with small scattered punctures; seen from above the width of 

 the anterior margin of the head not more than one half greater than 

 the cephalo-caudad length; head not receding behind the eyes; post- 

 ocellar line about one fourth shorter than the ocellocular line; third an- 

 tennal joint distinctly longer than the fourth; scutum shining with large 

 close punctures ; scutellum with close, sometimes confluent punctures ; 

 base of the propodeum depressed, coarsely rugose, the superior posterior 

 angles shining, obliquely rugulose, the sides and posterior face reticulate; 

 petiole strongly sulcat'e laterally, subequal with the length of the posterior 

 basitarsis. Black; head, thorax and petiole with long black hair; wings 

 dusky hyaline, venation pale brown, costa and stigma dark brown. 



Type Locality. — Camden County, New Jersey. Described from one fe- 

 male collected July 27, 1890. Named for W. J. Fox. 



Type.— Cat No. 21564, U. S. Nat. Mus. 



Pemphredon virginiana new species. — Female. — Length 10 mm. Clypeus 

 flat, shining, sparsely punctured, the anterior margin truncate with a 

 median tooth and prominent lateral angles so it appears feebly tridentate ; 

 distance between the eyes at the clypeus subequal with length of an eye, 

 front sparsely punctured medianly, striato-punctate laterally; posterior 

 orbits and vertex shining, sparsely punctured; seen from above the ante- 

 rior width of the head is not nearly twice as great as the cephalo-caudad
